The fastest way to change your alarm sound

Open the Clock app on your iPhone, tap the Alarm tab at the bottom, then tap Edit in the top left corner. Select the alarm you want to change, tap Sound, and pick a new sound from the list. Tap Back, then Done — the change saves automatically.

That's the complete process. You don't need to restart your phone or confirm anything else. The new sound will play the next time that alarm goes off.

Key Takeaways

  • The Clock app is where all iPhone alarms live, and you reach it from your home screen or by swiping up and searching for "Clock".
  • You must tap Edit before you can change an alarm's sound — tapping the alarm itself only shows you when it's set to go off.
  • iPhone comes with dozens of built-in alarm sounds, and you can also use any song from your Music app as an alarm.
  • If you want the same sound for multiple alarms, you have to change each one separately — there's no way to set a default for all future alarms.

Where to find the Clock app and your alarms

The Clock app is built into every iPhone and sits on your home screen by default, usually in the Utilities folder if you've moved it. If you can't find it, swipe down from the top of your screen and type "Clock" into the search box — tap the app when it appears.

Once you open Clock, you'll see five tabs at the bottom: World Clock, Alarm, Timer, Stopwatch, and Bedtime. Tap Alarm to see all the alarms you've already set up. If you haven't created any alarms yet, the screen will be empty, and you can create a new one by tapping the plus sign in the top right corner.

The Edit button is the key step most people miss

When you first look at your alarms, tapping one directly will only show you its time and which days it repeats — it won't let you change the sound. You have to tap the word Edit in the top left corner first. Once you do, each alarm will show a circle next to it that you can tap to select, and the alarm itself becomes editable.

After you tap Edit, select the alarm you want to change by tapping on it (not the circle). A screen will open showing all the alarm's details: the time, which days it repeats, the label, and the sound. The Sound option is usually near the bottom of this screen.

Choosing from built-in sounds or your own music

When you tap Sound, you'll see a list of alarm tones that come with iPhone. These include names like Alarm, Beacon, Bells, Chime, and Radar. Each one plays a short sample when you tap it, so you can hear what it sounds like before you commit. Scroll through the list to find one you like, then tap it to select it.

If you want to use a song from your Music app instead, scroll to the very bottom of the sound list and tap Pick a Song. This opens your music library, and you can choose any song you've downloaded or added to your library. The alarm will start playing from the beginning of the song when it goes off. Keep in mind that if you delete the song from your phone later, the alarm will revert to a default sound.

Saving your changes and testing the new sound

After you pick your new sound, tap Back to return to the alarm details screen. You'll see the sound name has updated to show your choice. Now tap Done in the top right corner to save all your changes. The screen will return to your alarm list, and your changes are already saved — you don't need to do anything else.

To test whether the new sound actually works, you can set a test alarm for one minute from now and wait for it to go off. This is especially useful if you picked a quiet sound and want to make sure you'll actually hear it when you need to wake up.

Why you might not hear your alarm even after changing the sound

If you've changed the alarm sound but it's still silent when the alarm goes off, check whether your phone is in Silent mode. On the left side of your iPhone, there's a physical switch that toggles between Silent (when you see an orange line) and Sound On. Silent mode mutes alarms, so flip the switch toward the back of the phone to turn sound back on.

You should also check your volume settings. Go to Settings, tap Sounds & Haptics, and make sure the Alarm Volume slider is turned up. Some people accidentally lower this slider while adjusting other volume settings and don't realize it affects alarms separately from call volume or music volume.

Creating a new alarm with a specific sound from the start

If you want to create a brand-new alarm and set its sound right away instead of changing an existing one, tap the plus sign in the top right corner of the Alarm tab. Set the time by scrolling the hour and minute wheels, then tap Save. The alarm will be created with the default sound, and you'll need to edit it to change the sound using the steps above.

There's no way to set the sound while creating the alarm — you always have to create it first, then edit it to pick a different sound. This is one of the quirks of how the Clock app works, but it only takes an extra 10 seconds.

Frequently Asked Questions

Can I set different alarm sounds for different days of the week?

No. Each alarm has one sound, and if you set it to repeat on multiple days, it uses that same sound every time it goes off. If you want different sounds on different days, you have to create separate alarms for each day and give each one its own sound.

What happens if I delete a song I used as an alarm sound?

The alarm will still exist and go off at the right time, but it will play a default sound instead of your song. If you want to use that song again as an alarm, you'll need to re-read it to your phone and then edit the alarm to select it again.

Can I use a voice memo or a sound I recorded myself as an alarm?

You can use a voice memo if you've saved it to your Music app or Voice Memos app, but the process is limited. Most custom recordings won't show up in the alarm sound picker unless they're in a specific format. Your best option is to use a song from your music library instead.

Why does my alarm sound keep changing back to the default?

This usually happens if you're using a song as your alarm sound and that song gets removed from your phone or your music library. Check whether the song still exists in your Music app. If it does, edit the alarm and re-select the song to fix it.

Can I make the alarm sound louder or quieter without changing the actual sound?

Yes. Go to Settings, tap Sounds & Haptics, and use the Alarm Volume slider to adjust how loud your alarms are. This slider is separate from your regular volume controls, so you can have quiet music but loud alarms, or vice versa.
